the diagram shows a simple pendulum swinging backwards and forwards between P and Q one complete oscillation of the pendulum is when the bob swings from p to q and then back to p​

If the speed of a particle triples ,by what factor does its kinetic energy increase?

Arotating space station is said to create “artificial gravity”—a loosely-defined term used for an acceleration that would be crudely similar to gravity. the outer wall of the rotating space station would become a floor for the astronauts, and centripetal acceleration supplied by the floor would allow astronauts to exercise and maintain muscle and bone strength more naturally than in non-rotating space environments. if the space station is 200 m in diameter, what angular velocity would produce an “artificial gravity” of 9.80 m/s^{2} 2 at the rim?

If jerome is swinging on a rope and transferring energy from gravitational potential energy to kinetic energy, is being done.
